OK. But is it still OK with setq and a list? By the way, perhaps this is something the compiler should warn about? I took this opportunity to try to do something cool, namely to use the Emacs --batch gear to operate on a set of files, but *without* having to reload the configuration each time (for each file), which is the case if one does a shell (bash, zsh) loop with the -u option, and it just kills speed if you have just a couple of files. This turned out a bit more complicated than at first sight. I was trying to save time :) ;; This file: http://user.it.uu.se/~embe8573/conf/emacs-init/batch.el ;; emacs --batch -u USER **/*.el -f fix-hooks-in-batch-args (require 'cl-macs) (defun fix-hooks () (while (re-search-forward "(setq \\(.*\\)-hook\\([[:blank:]]*\\)'\\([^(].*\\))" nil ; no BOUND t) ; NOERROR (replace-match "(setq \\1-hook\\2'(\\3))") ) (when (buffer-modified-p) (save-buffer)) ) (defun fix-hooks-in-batch-args () (cl-dolist (file-rel (cdr command-line-args)) ; drop initial 'emacs' (let ((file (concat command-line-default-directory file-rel))) (when (file-exists-p file) ; drop options and 'fix-hooks' (find-file file) ; - better way to filter files?
